Elevation and pitch measuring arrangements for track construction machines, in particular for track straightening machines.

The rails of a railroad track must be laid out in such a way that the track layout in the area corresponds to the established route plan. In addition, the rails of the

When viewed in the horizontal plane, the tracks should not be wavy, they should be in a straight section of track also really run in a straight line, and in an arcuate shape guided track section, they should correspond to the prescribed radius of curvature. Bs are track laying machines known who mesaen the laid track in this regard and the rail position by means of hydraulically operated and the rail arranged on the machine correct shifting directional organs.

Essentially the same requirement applies to the rail guide in the vertical direction. The French patent specification 657 880 describes a track testing machine, which both the registration of the horizontal rail guide and the registration of the vertical components of the rail. tracking and track width to be continuously registered. The vertical component of the rail guide here refers to both the elevation of the two rails to understand each other in a curve as well as the gradient or the gradient of the rails in the longitudinal direction. Included In particular, it concerns errors resulting from a waviness of the rail guide in the vertical plane exist to bring to the display.

This known arrangement uses a pendulum assembly for displaying the rail superelevation and displaying the waviness W of the rail guide speed in the vertical plane, two on the machine tensioned tendons different length, if the tendon end points are not aligned with each other, have their tendons middle height differences.

The Austrian patent specification 2 04-7 899 and this Application associated additional application 9 A 9743/65 (published January 15, 1967) show measuring devices for measurement and registration d, he rail cant and the rail slope or their slope in the longitudinal direction using

communicating tubes, of which such a pair of tubes, which of the measurement of the rail slope or the rail slope serves, is arranged in the longitudinal direction of the vehicle, while one is used to measure the cant communicating tube device in the transverse direction of the Vehicle is arranged.

Both a pendulum arrangement and such relatively long devices consisting of communicating tubes have the disadvantage that they are dampened by Require additional funds, otherwise they will only deliver oscillating measured values.

The invention describes such a measuring system which is free from these disadvantages.

An arrangement for measuring the rail camber and the Vertical error of the rails of a track on a track construction machine in particular track straightening machine is characterized according to the invention in that on the machine at a distance from each other two on the two. Rails of the track running pairs of wheels are arranged, the wheels of which can be moved in the vertical direction independently of one another, and that between the wheel axles of the wheels of the two pairs of wheels running on the same rail they connect

Rods or tendons are arranged and a connecting tendon is stretched between the centers and that near and parallel to the tendon one with running wheels also on the Rails running measuring axis is arranged and on the measuring axis a level having electrical contacts supporting pivotable arm and at least one at its end an eotodiode arrangement for scanning the relative Height of the tendon-bearing arm are arranged and the pivoting arms each have a servomechanical adjustment device is assigned, the one with pens for recording the superelevation angle and the altitude migration the chord are connected relative to the measurement axis.

An embodiment of the invention is shown in the figures. From the figures show:

be. Another pair of wheels consists of wheels 2, 2 * and their axle 4. Two connecting rods 7, 8, which can also be ropes, connect axles 3, 4 near wheels 1 and 2 or 1 »and 2 ¹ . The wheels 1, I ¹ , 2, 2 ¹ are arranged on the vehicle so that they can adjust independently of one another in the vertical axis

The centers of the rods or ropes 7, 8 are through a tendon 9 connected to each other. Parallel to the chord 9, a measuring axis% whose wheels also extend on the rails

movable inclination.

On the Hess axle 10, two pivotable arms 11, 13 are arranged, which are pivotably attached to the posts of the two bridge arms 20, 21. The arm 11 carries a level 12 with electrical contacts. On the bridge 20 there is arranged a adjusting motor 15 controlled by the level 12, the axis of which forms a spindle which adjusts the arm 11 in a horizontal position Clockwise or counterclockwise rotation takes place through the level 12 having the electrical contacts.

A similar pivotable arm 13 is arranged on the post of the bridge arm 21. There are two photodiodes on the arm 13 14 arranged, which control the adjustment motor 16 provided on the bridge 21. The motor axis of the Motor 16 also forms a spindle that has an angular, moderate adjustment .des arm 13 causes until the photodiodes 14 are aligned with the respective height 'of the measuring chord 9. 18 is an illumination lamp associated with the photodiodes.

Height tracking devices are controlled by photodiodes

The measuring principle results from FIGS. 3 to 6.

In these figures, 00 denotes the horizontal line. In Fig. 3, the left rail is elevated compared to the right rail; For this reason, too, the arm 11 is swiveled somewhat upwards with respect ^{to a straight line 10 f parallel to the measuring axis 10.} This pivoting, caused by readjustment by the motor 15, is recorded by the pen 18. The measuring tendon 9 has its position in relation to the

and accordingly the arm 11 became with respect to the / measuring axis 10 parallel straight lines 10 'swiveled slightly downwards » This means a deflection of the pen 18 towards' the opposite side.

In FIG. 5, the measuring axis 10 is opposite to that assumed as the zero position Line 0-0 lowered, but runs parallel to the line 0-0. This corresponds to the case that both rails are slightly lower than the measuring axis 10 at the point Rails on axes 3 and 4. Correspondingly, the chord 9 appears at a greater height than the measuring axis 10, and the adjusting motor 16 accordingly has the arm 13 swiveled up. This pivoting is recorded by the pen 19. .

In Fig. 6, the reverse case is assumed, i. H. the mess axis 10 appears higher than the straight line Ö-O and you Distance compared to tendon 9 is less. Correspondingly effected the photodiode arrangement 14 a lowering of the arm 13 in the direction of the measuring axis 10. This lowering of the arm 13 is also by the pen 19, but as a deflection in the opposite direction compared to Fig. 5, registered.

Instead of a pivotable 9 approximately in the middle of the transverse antenna To arrange arm 13 on the measuring axis 10, the height deviation the center of the transverse chord 9 measured and registered with respect to the measuring axis 10 can also be done at the two ends the transverse tendon 9 »in the immediate vicinity of the longitudinal rods or longitudinal tendons 7, 8 each have such a pivotable arm 13 be arranged on the relative height of the measuring axis
